VALVE.

Specification of Letters Patent.

.Patented Oct. 13, 1908.

Application led February 21, 1907. VSerial No. 358,618.

l To all whom it may concern.'

4'Be it known that I, MARTIN S. WiLooX, residing at Middleport, in the county of Meigs and State of Ohio, have invented certain new and useful Improvements in Valves,

of which the following is a speciication.

My invention relates to certain new and useful 1m rovements 1n valves, and 'it more particular y relates to valves for use on boiliront section having a removable valve seat to coperate with the valve roper, While the back section has a web t rough which a valve guide rod passes. A stufin box is formed on thefront section throu which the valve stem passes and joins wit the operating mechanism,

In its more' detail nature my invention includes certain novel construction, combination and arrangement of arts, all of which will be `iirst described in etail, and then be s eciically `pointed out in the appended c aims, reference being had to thefaccompanying drawings, in which:- v

Figure 1, is a side elevation of my, invention. Fig. 2, is a central,vertical longitudinalsection thereof. Fig. 3,' is a cross section onthe line 3-3 of Fig. 2, looking toward the front section. Fig. 4, is a similar view on the same line looking toward the back section. Fig. 5, is a central, vertical longitudinal section of a modiied form of my invention. Fig. 6, is a detail view of a modied form of my invention, showing the modified arrangement for joining the casing sections.

Referring now to theaccompanyin drawi ings, in which like letters and num ers of reference indicate like parts in all ofthe figures, 1 designates the rear section ofthe valve casing which comprises a threaded end 1a to screw intol the boiler aperture, the flan e 1b and the internal web 1 within the ilui passage 1, as shown. The web 1c has a bearing aperture 1d tol permit passage of the valve guide rod 6 hereinafter again relvided with a series of dowel y it may ferred to. The front section 2 has` a threaded end zato' correspond with the iiange 1b of the rear section 1 and to coperate with the union 3 whose flange 3b abuts the flange 1b and' whose internally threaded end 3 cooperates with the threaded end 2 ofthe section 2. A nut portion 3c is provided on the union 3.

Each section 1 and 2 has its abutting face formed with a shallow annular groove 1"-2x to receive a washer 10 which may be in the nature of a copper or other soft metal wire and the two sections are further locked together from turning with respect to one ancoL other bydowel pins 10a. One section is propin receiving apertures 10b to enable the'sectlons to be relatively rotated to adjust them to any desired position.

The front section 2 has a passage 2'3 and a valve seat or socket 2 to receive the valve seat 2d which maybe held therein by friction, as shown in Fi 5, or by thread' the socket and seat toget er, as shown in i 2.

2f designates the spout portion o the front section 2 whose mouth may be threaded as at 2g if desired to receive an olf-take pipe, not shown.

The valve 4- ispreferably of the winged typel and has' a center boss projecting from its rear face,'which boss has a bore 4:* to receive theend of the rod 6 which is secured in place by a in 4b or otherwise. At the liront` the valve 4 as a second boss 4 likewise a ertured to receive the valve stem 5 which, iks the rod 6, is secured to the valve by a pin 4, as indicated.

The stem 'passes' through the projection 2h which has an aperture 2r for the stem, the stem being pivoted to the operating vlever 7 vby a pin 5a which; asses through an elongated slot 7a in the ver 7, the lever 'Z being pivoted at 7"` to lugprojecting from the spout portion of the section 2.

' Instead of securing the stem 5 to the lever 7 to be o crateri as a push stem, and as shown in Fig. 5 maybe adopted, fi. e., the stern 5 may be threaded as at 6b and the projection 2h also threaded to coperate with the threaded 1g. 1, the arrangement shown in portion 6h of the stem 6, and a hand wheel 8 may be secured on the stem whereby the same may be turned to seat or unseat the valve as the case may be.

If desired the valve e may be coned as at 4 on its rear face, (see Fig. Al) to enable it to be readily opened against fluid pressure, and When-the form of my invention shown in Fig. 1 is used the valve will automatically seat itself by-iiuid pressure. vt By roviding the rod 6 as shown and describe should any mud or sediment lodge at the rear of the web 1c or at the opening of the chamber 1e in th'e rear section 1, the movement of opening and closing of the valve will cause the rod 6 to reci recate and thereby loosen the sediment an permit the same to blow out. The web 1c also serves to limit the movement 'of the valve 4 when being opened and prevents its being totally withdrawn from its seat.

' From the foregoing description taken in connection with the accompanying drawings it is thought that the co'r'nplete construction, operation and numerous advantages of my invention will be readily understood by those skilled in the art to Whichthe invention a pertains, and it will furthermore be seen t at I have provided a valve of a very simple and efective construction in which the parts can be easily repaired when necessary, by simply loosening the union 3 to release the front section When the. parts may 'be separated and the valve seat (and the valve if necessary) may be easily taken apart and renewed.
